I think contextualizing the applications of a tool like Unpaywall in the OA movement could be useful in the 5.3 section, as an added paragraph. Unpaywall helps researchers find papers that are available freely on the web. Often these papers are held in university repositories or author websites. The author may have transferred copyright to the publisher at the time of publication for a window of time that has expired, or the author may have retained copyright of their publication. I think that the idea of a scientific language decoder for the public is an excellent educational tool and potential public service.
